In capitalism, the economy that controls how people are fed, clothed, sheltered and educated is run by successful private capitalists. These people are lucky and/or skilled at exploiting their employees. To reward them for their shrewdness, they get to control part of the economy. Since the economy answers basic needs the government ought to answer, there is no reason a democratic society lets these important positions be filled by luck, rather than by election. Free enterprise is not naturally democratic, but in it’s very nature, an undemocratic system.
